Icelandic investigative journalist and former WikiLeaks spokesperson Kristinn Hrafnsson is set to become the whistleblowing organization’s new editor-in-chief, replacing isolated founder Julian Assange in the role.

The announcement was made late Wednesday in a statement issued through the WikiLeaks’ official Twitter account.

The statement cites the “extraordinary circumstances” of WikiLeaks’ founder and former editor-in-chief Julian Assange’s “arbitrary detention” as a reason for the move.
